Here’s an educational film released in 1976 by Counselor Films to teach wild and unruly yoots why graffiti is stoopid. The first minute or so of Graffiti: Fun or Dumb? is truly laugh-out-loud funny.

Using kids’ own arguments (both pros and cons), film presents overwhelming evidence that vandalism is dumb. Shows that graffiti-type vandalism costs over $20,000,000 a year.

 
The short film is available for purchase at A/V Geeks.
